GLASS-BAR BRACKET FOR LOOMS FOR WEAVING SILK RIBBON OR FRINGE.

SPECIFICATION forming part of Letters Patent No. 440,370, dated November11, 1890.

Application filed September 12, 1889. Serial No. 323,753. (No model.)

T0 to whom it nutty concern:

Be it known that I, OTTO W. SOHAUM, of the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulGlass-Bar Bracket for Looms for lVeaving Silk Ribbon or Fringe, of whichthe following is a true and exact description, reference being bad tothe accompanying drawings, which form a part of this specification.

My invention relates to the construction of the brackets which aresecured upon the warp-guidingbeams, over rods supported upon which thewarp-threads pass, and to breastbeams of ribbon and other narro w-warelooms, and which support the rods (generally of glass) over which thewarp-threads and finished fabric pass; and the object of my invention isto provide such brackets as will be at the same time firm and secure intheir hold on the beams and rods and easily adjusted along the same toadapt the loom to fabrics of varying width.

My invention will be best understood after a description of the drawingsin which it is illustrated, and in which Figure 1 is a sectional viewtaken across the warp-guiding beam as secured to the loomframe, showingmy improved bracket in place thereon. Fig. 2 is a side view of thewarpguiding beam, showing two of my adjustable brackets secured thereto.Fig. 3 is an enlarged' side view of my adjustable bracket constructed inwhat I believe to be the best form for use on the warp-guiding beam.Fig. 4; is an edge View of the same. Fig. 5 is a side view of whatIbelieve to be the best construction of my improved bracket for use onthe breast-beam. Fig. 6 is an edge view of the bracket shown in Fig. 5.Fig. 6% is a section through the shank of the bracket on the line a: wof Fig. 6. Fig. 7 is a view of a modified form of bracket, especiallydesigned for use on the warp-guiding beam; and Fig. 8 is a View showingthe same general construction as Fig. 7, further modified to fit on a cylindrical beam.

A, Figs. 1 and 2, is the frame of the loom.

B is the warp-guiding beam, connected with the frame by standards 5.

B, Figs. 5 and 6, is the breast-beam, supported in the usual way, as bystandards I).

B represents a beam made of asection of tubing. As my invention requiresno change in the ordinary form of the loom and its beams, it isunnecessary to show these old and well-known parts in the drawingsfurther than enough to show how my improved brackets are attachedthereto.

0, Figs. 1, 2, 3, 4, 7, and 8, indicates the warp-guiding beam-bracket,my preferred form of construction being that shown in Figs. 1 to 4:,inclusive.

The bracket shown in Figs. 5, 6, and 6% is especially adapted for use onthe breast-beam, although all the modifications of my device shown canbe applied on either beam.

0 in each of the figures represents the bottom or under bearing for theglass-supporting rods K, and O is the upper bearing, between which andbearing 0 the rods are clamped and held.

The main features of my invention consist, first, in making the bracketadjustable along the beam upon which it is used by means of a clampcombined with it and by which it can be readily connected anddisconnected with the beam, and, second, in so combining the upper andlower bearings for the rods and the clamp that the bearings are clampedand unclamped as the bracket is secured or loos- 'ened on the beam.

In my preferred warp-guiding beam-bracket the lower bearing C is formedof a casting having a broadened base 0, adapted to rest on the top ofthe warp-beam, and ears 0, adapted to extend down on each side of thebeam for a short distance. The upper face a of this casting is alsobroadened and formed with recesses c 0 arranged on a gradually-ascendingplane to receive the rods K, over which the warp-threads L pass, asshown in Fig. 1. The upper bearing-piece O has a lower face 0corresponding to the face 0 of the lower bearing and is provided withrecesses 0 which should be in a plane parallel to the top of the beam B,as shown. Into these recesses o extend the inwardly-bent ends 0 of astirrup-iron G which extends beneath the beam and is provided with athreaded perforation c on its under side, in which works a screw E, theend of which is forced up against the bottom of the beam in order tocause the stirrup-iron to draw down upon the upper bearing-plate Ccausing it to clamp the rods K tightly between itself and the lowerbearingplate 0', and also clamping said lower bear- 1ng-plate againstthe top of the beam.

In the plan shown I secure on the end of screw E, by means of a simpleform of balland-socket joint, a broadened pressure-piece E, so as toallow a certain freedom of adustment to the parts when being clampedtogether.

In brackets, as heretofore, made of wood the recesses 0 have been cutout of the wood and carefully fitted to the rods which rest in them. Inmy device, Where the bearing-pieces O C are preferably of metal andwhere frequent changes in position are contemplated, it would beimpossible to form the recesses to accurately fit the rods, especiallyas the rods generally vary somewhat in cross-section at different pointsalong their length, and I accordingly use abed D, preferably of leather,molded to fit the recesses 0 and which will by reason of its yieldingcharacter fit closely on any section of rod that may be clamped betweenthe two faces on the castings C and C Felt or other similar yieldingsubstances can of course be used instead of leather.

In the modified form of the device (shown in Fig. 7) the lowerclamping-piece rests upon the beam, as in my preferred form, but isprovided with a downwardly-reaching arm F, with hooked end F adapted toextend beneath the beam, as shown, and an inwardlyinclined horn Fextends up from its top on the same side, while in its opposite side athreaded perforation F is formed. The upper clamping-piece is providedwith a wedgelike end G adapted to extend beneath horn F and at itsopposite side it has a downwardly-extending arm G, arranged to restagainst the side of the beam and having a perforation G, through whichpasses a screw E. It is obvious that the action of said screw whenengaged with the threaded perforation F will be to draw thebearing-pieces together on the rods and clamp the bracket to the beam.In Fig. 8 is illustrated a construction similar to that of Fig. 7, savethat the arm G has an inwardly-extending end or hook G which isespecially adapted to engage a beam of cylindrical form.

In Figs. 5, 6, and 6% is illustrated still another modification of mydevice, which, as aforesaid, is especially adapted for the breastbeam.In this modification the lower bearing-piece C does not, as in the otherdescribed constructions, rest upon the beam, but by means of adownwardly-extending arm H rests against the side of the beam. This armH has horizontal projections h at its lower end, which extend beneaththe beam and should have roughened surfaces, as indicated in Fig. 67 toenable it to take a better hold 011 the beam, and it (arm H) is coredout to the U form (shown in Fig. 6%) to admit a bolt J, which alsopasses through a perforation I in the upper clamping-plate 0 upon thetop of which the bolt-head J rests. The clamping-plate C has a U shape,one arm Iextending over the lower plate 0 and resting upon the rod K,while the other arm 1 extends over a projecting ridge b" on the beam B,as shown. On the threaded end J 2 of the boltJ a thumb-nut J 3 screws,and, as will be at once seen, the action of the nut on the bolt andthrough it on the clamping-plates is to draw said plates together andclamp them tightly on rod K and on beam B.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A bracket for narrow-ware looms, having, in combination with abearing for the warpguiding rods, a clamp whereby the bracket can be adjustably secured to the warp-guiding or breast beams of the loom.

2. A bracket for narrow-ware looms, having, in combination, an upper andlower bearing for the warp-guiding rods, and-a clamp arranged to holdthe bracket upon the warpguiding or breast beams of the loom and at thesame time to clamp the upper and lower bearings together upon the rods.

3. A bracket for narrow-ware looms, having a lower bearing-plate for thewarp-guiding rods arranged to rest on the top of the beam, incombination with an upper bearing-plate, and a clamp arranged to holdthe bracket upon the beam. and at the same time clasp the bearing-platesupon the rods.

4. A bracket for narrow-ware looms, having a lower bearing-plate for thewarp-guiding rods arranged to rest on the top of the beam, incombination with an upper bearing-plate, and a clamp consisting of astirrup-iron 0 adapted to extend beneath the beam and engage the upperbearing-plate on each side, and a screw E at the bottom of saidstirrupiron and arranged to bear upon the under side of the beam.

5. A bracket for narrow-ware looms, having a lower bearing-plate for thewarp-guiding rods arranged to rest on the top of the beam, incombination with an upper bearing-plate, and a clamp consisting of astirrup-iron 0 adapted to extend beneath the beam and engage the upperbearing-plate on each side, and a screw E at the bottom of saidstirrupiron having a pressure-piece E secured to its end by aball-and-socket joint and arranged to bear upon the under side of thebeam.
